One thing I can suggest added to the finding the ice staff piece, you must dig when it's snowing in 3 different locations, one will be found between spawn and workshop, one between workshop and church, and one around church and gen 6. If's it's snowing when you leave the spawn there will only ever be one staff part before you get to the jug/stamina-up area.

I just re-read your whole post and there's a few other things missing. There are 8 switches for the lighting upgade. The fourth one you don't have a location is by the wind tunnel entrance in the footprint, panel 7 is in the workshop right before going into no mans land and then the one on hte excavation site is number 8. And the last piece to the shiel can also be found in the footprint by jug where the chest is.

hahaha nice one only a few hours left!! one thing i hate though is the amount of threads that say when is it coming??? the dlc has dropped the same time every time give or take 15mins to half hour. how do people not understand.
